increased nose dive

recently I have been noticing increased nose dive when braking and more body roll when turning. its wasn't really bothering me but it was noticeable. I figured with 60k on the odometer that my shocks were probably shot. The other day I jumped under my rig to tighten some leaking fittings on my OBA tank and happened to look at my left front bump stop. It was f**ked!

I ordered new OEM stops and installed.

Super easy. Notice how much the original bump stops have compressed in 60k miles. With the front end up in the air I decided it was time to crank the T-bars (again). This time up to 23 1/4. went for a drive and was impressed at how much better the ride felt, even with the t-bar crank. I would highly recommend anyone that feels their ride quality has diminished to drop the $35 and replace the springs(bump stops). I don't even feel the need for the extended TD stops(at this time). on a side note, my t-bars required 7.5 turns on the left and 1.5 on the right. both were sitting at about 21 1/2, although left side was sitting a bit lower than the right. seemed odd to me that they would require such a vast difference in turns.

Wait so your T-bars are cranked and it drives okay with stock bump stops?

With the alpha it drives great with stock bump stops (if leveled to 23.25")
The aftermarket ones are stiffer, make the truck ride harsher. They even decrease uptravel (for wheeling). I noticed with stock stops I can get my tires to barely rub the top of the fenders in extreme situations too.

You gotta remember alphas have stiffer torsion bars for the extra weight of the v8. That may combat some of the nosedive some I5 people experience. I had the dealer replace my bumpstops when I bought my truck. I put on 5100s and TD bumpstops when I leveled it. It rides good down the street but I plan on putting the stock ones back in for wheeling. I need to go crank the bars up about 1/2". They've dropped a little and I'm pretty sure the front end is now really sitting on the stops instead of a tiny gap.

That is really good to know, I was planning to get 5160's for my Alpha and if I can run the stock bumpstops that would be great.

Im running 5160s upfront. Theyre amazing on the high speed stuff, wish there was something like it for the back!

Is replacing the bump stops easy? Because well, haha I'm down a bump as of 5 minutes ago it was so old the head sheared off because of a pot hole.

I can and have removed and replaced the bump stops with my bare hands...no tools required...really.

Just wondering cause I've never touched them before, cause I guess I might as well do both now this weekend, any tips or write up possibly?

To remove the bump stops: grab with your hand and pull.
To install new ones: grab with your hand and push. :) Actually, for installation it's a bit easier if you hit the base with dish soap (lubricant that will wash away) and insert base past one of the three "feet" in the older. Then use a flat screwdriver with the tip wrapped in a towel to dull it, push up on the base to force it under the other feet.

BTW, if you want to read a decent article on how torsion bars and these "progressive dampeners" aka bump stops work, check this out: http://www.gmfullsize.com/tech/torsion401.html. It's not a flawless article but it helps demonstrate the difference between the OEM bump stops and the stiffer aftermarket ones.

Yep. Been on oem bumpstops, t-bar crank, 35" MTR tires a week after the truck left the dealer lot in 09.
Though I am on fox shocks now the oem adventure shocks are a real good option for the alpha to consider also.
I carry them as my trail spares now. Theses are the last part#s I had referenced.
Adv Shocks:
